Ted Ligety won his second Winter Olympics gold medal eight years after his first by powering to victory in the men's giant slalom.
Ligety, whose only triumph at the Games before Wednesday was in the combined at Turin 2006, was in a class of his own and laid the groundwork for his triumph with a first run that left him almost one second clear of the rest of the field.
The American overcame a couple of nervy moments in his final run to post an overall time of two minutes 45.29 seconds, which was enough to clinch top spot by 0.48secs ahead of runner-up Steve Missillier, whose fellow Frenchman Alexis Pinturault took bronze.
Finland secured gold in the cross country men's team sprint final after Sami Jauhojaervi held off the challenge of Russian Nikita Kriukov in the home straight.
There was drama in the closing stages of the race as Germany's Tim Tscharnke took a tumble in the middle of the three-man leading pack.
That fall allowed Teodor Peterson to ski ahead and earn a bronze medal for Sweden, with Tscharnke finishing seventh after regaining his feet.
Ingvild Flugstad Oestberg and Marit Bjoergen led Norway to victory in the women's event.

Vic Wild claimed gold for hosts Russia in the men's snowboard parallel giant slalom final, minutes after seeing his wife Alena Zavarzina win bronze in the women's event.
US-born Wild, who became a Russian citizen two years ago, beat Nevin Galmarini in the big final at Rosa Khutor Extreme Park, overcoming a first-run deficit to see off the challenge of the Swiss.
Wild had first got past Patrick Bussler in the last four, with the German then missing out on a bronze medal in the small final to Slovenia's Zan Kosir.
Shortly before the men's event, Switzerland's Patrizia Kummer walked off with gold in the women's race after Tomoka Takeuchi of Japan fell in the second run of their showdown.
Reigning World Cup champion Kummer, 26, beat home hope Zavarzina in the semis to set up a final against Takeuchi, who benefited from a slip by Ina Meschik in their last-four tie.
Zavarzina then took bronze in the small final before she watched her husband's success.
